The Map of the Region Between New Zealand and the Antarctic is a color map, measuring 12.75 x 20 inches, captioned, "Showing the routes of the "City of New York" and, so far as available, the soundings made on these voyages." The map indicates that the soundings were made with a sonic depth finder as communicated to the American Geographical Society by Rear Admiral Byrd, and that the map as a whole was made to demonstrate the lack of available soundings between New Zealand and Little America. The map is copyrighted 1930, by the American Geographical Society of New York.
